IMPROVEMENT lN l-IDGE SETTING AND BURNISHING TOOLS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 196,288, dated October 23, 1877; application filed- August 1, 1877.

To all whom "it may concern Be it known that 1, JAMES H. BUsELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Edge Setting and Burnishing Tools for Boots and Shoes, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to a tool for setting and finishing the edges of boot or shoe soles or heels, adapted to be used by hand or in a machine; and it consists, first, in applying to a burnishing-tool, adapted to set andfinish the edge of a sole or heel bybeing reciprocated or oscillated to and fro in contact therewith, a rand-guide mounted upon a spring, and adapted to be moved endwise to accommodate the length of its projection beyond the burnishing-surface of the tool to the varying projection of the sole beyond the upper.

My invention further consists in the use, in combination with a burnishing-tool adapted to finish a hollow or concave edge on a sole or heel, of a pivoted apron or guardplate extending across the burnishing-face of the tool, and adapted to press against the tread-surface of the sole, and automatically accommodate its position to the varying thickness of the sole or heel, its inner edge moving in close proximity to the curved surface of the burnishing-face of the tool.

My invention further consists in forming, in the face of the burnishing-tool, one or more grooves, extending across said surface at right angles to the direction of motion of said tool when in use, in combination with a yielding apron or guard-plate adapted to press automatically against the tread-surface of the sole, and adaptitself to thevaryingthicknesses thereof, and provided, upon its inner edge, with one or more teeth to fit said grooves, to prevent the formation of a feather-edge on the outer corner of the sole or heel.

Figure l of the drawings is a front elevation of my improved tool adapted to handuse. Fig. 2 is a side elevation. Fig. 3 is a central longitudinal section. Fig.4 is an in verted plan. Fig. .5 is an elevation of the rand-guide removed from the tool, and Fig. 6 is an elevation of the'apron or guard-plate detached from the tool.

A is the burnishing-tool stock, provided with a shank, A, by which it may be secured in the handle B for hand-use, or in the toolcarrier of any of the many edge setting and burnishin g machines, in which the tool has imparted to it a reciprocating or oscillating motion.

The burnishing-face a of the tool A is made convex in two directions, and has formed therein one or more grooves, 1), extending across it at right angles to the line of motion of said tool when in use, said groove or grooves dividing said burnishing-face into two or more distinct and separate burnishing ribs or surfaces, the corners of which adjacent to said grooves are rounded, to prevent injury to the sole-edge by the scraping or cutting of the sharp corner that would otherwise be presented. 1

O is the rand-guide, made in form shown in Figs. 1, 3, and 5, and fitted to a bearing formed in the tool A, and resting on the spring D in such a manner that it may move vendwise to adapt the length of its projecting portion to the varying width of the projection of the sole beyond the upper, so that the best possible guide for the burnishing-tool may be hadwithout danger of injury to the upper by burning or cutting it with the edge of the rand-guide.

The spring D is secured to tool A by the screw 0, and its movable end engages with shank G of the mud guide 0, as shown in Fig. 3.

E is an apron or guard-plate,provided with two arms, ff, adapted to embrace the tool A,

towhich it is pivoted at g, in the axis of the curve 1' e of the convex face of the tool A, in such a position that the inner face or edge of the apron E will be in contact with the face of said tool at whatever distance from the .randguide it may be placed within the limits of the width of the tool A.

The inner edge of the apron E has formed thereon one or more teeth, j, which project into the grooves 1) beyond the working face of the toolA, to prevent the formation of a featheredge upon the outer corner or tread-surface of the sole.

The apron E is held hard against the treadsurfaee of the sole by the tension of the springs k k, connected at one end to the arms ff, and at the other end to the T-shaped stand F set in and projecting from the edge of the tool A,

said springs allowing'the apron to yield and 7 move along'the curved burnishing-surface of the tool A as the sole increases: in thickness,

'moving about its pivot g in an obviions'manner; 7 By the use of my improved tool, either by hand orinamaehinathe whole edge of boot or shoe sole maybe finished without change: of tool, it onlybeing necessary to change the relativeposition of: the :tool and sole-edgeini passing from the beveled shank to the 'fore' 5 part, asindicatedin' Figs; land 3,'where the relative positions of the sole-edge: are; shown in dotted lines. 7 r a a r i a V V L I do not claim, broadly, ayielding rand-guide or a yielding tread-guard, for :I :am; aware such devices ofpeculiar construction have been: 7 used separately 5' but 7 7 a a a i 1 'What I- claim as new; and :desire to secure byLet-ters Patent of the UnitedStates, is 1 i I V r 1.
